If you can fit your hardware in it, go for the Sugo 4.
Do note, its really small and cramped to work in and there's no almost no clearance between a stock cpu cooler and the PSU.

Built an i5 rig for a customer of mine using the Sugo 4, with a Corsair H50 inside. Tight fit, but managed to install a Vertex SSD, a 1 Tb Black and a DVD burner. Nice little rig for someone on the go. I did use the Silverstone PSU with shorter cables.
